Find the solution of 3 times the square root of the quantity of x plus 5 equals negative 9, and determine if it is an extraneous solution.

 x= 4 is an extraneous solution.

Step-by-step explanation:

Since we have given that

We need to find the extraneous solution.

So, our equation becomes,

Now, we will check that x = 4 is an extraneous solution.

Hence, x= 4 is an extraneous solution.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
